CLAMP FOR GARMENT-SUPPORTERS.

Specification of Letters Patent.

Patented Dec. 14, 1969.

Application filed February 6, Y1909. Serial No. 476,540.

To all whom fit may concern'.

Be it known that I, BRUNO LAUciiNnn, a subject of the German Emperor,and residing at Olbernhau, Germany, have invented certain new and usefulImprovements in Clamps for Garment-Supporters, of which the following isa specification.

On April 16, 1908, I filed an application for United States LettersPatent for improvements in el-astics, Ser. No. 427,353, in the originalpresentation of which claims were made to the metal clamp for securingthe body of the elastics or the fabric to the fastening means at theends thereof. These metal clamps having been deemed a separateinvention, the claims to them have been eliminated from said priorapplication and embodied in this application.

The present invention therefore consists of the construction,arrangement and combination of the parts of the metal clamp of thischaracter, whereby the body of an elastic garment supporter or likearticle may be properly secured to the means provided at each endthereof for fastening the completed device in operative position on thegarment or garments, all as will be hereinafter fully described andafterward specifically claimed.

In the accompanying drawing, which illustrates the subject matter of thepresent application, Figure 1 is a plan view of a sheet metal blank ofwhich may be formed my improved clamp. Fig. 2 is a similar View of theblank illustrated in Fig. 1 stamped into form for my improved clamp andready to be bent into its operative form. Fig. 3 is a view in elevationof my improved clamp in position securing two parts together'. Fig. ilis a view in side elevation thereof. Fig. 5 is a detail sectional viewon the broken line 5-5 of Fig. 3. Fig. 6 is a detail sectional View onthe broken line 6 6 of Fig. 3. Fig. 7 is a view in elevation `of a clampmade in accordance with my improved invention but slightly modified inconstruction, in operative position securing together the body of thegarment supporter and the fastening means, parts of said body andfastening means being broken away.

Like reference characters mark same parts wherever they occur in thevarious figures.

Referring specifically to Fig. 1, the metal blank of which my improvedclamp is to be formed, and which may be stamped from sheet metal or evencast of malleable iron, although sheet metal is preferable, is ofsubstantially oblong form, comprising, around a central aperture S,parallel sides 9 and 10 and parallel ends 11 and 12, the side 9 and ends11 and 12 being plain, without projections or indentations, whileprojecting from the inner side of the side 10 is a tongue 13 and fromthe outer side thereof, and opposite the tongue 13, a similar tongue 1-1projects. While the operation of cutting out the blank of F 1 justdescribed and bringing it to the construction shown in Fig. 2, might besimultaneous or a single operation, I will describe the formation of thestructure shown at Fig. 2 as a second operation, during which the side 9is curved outwardly at 16 and the side 10 at 17, the end 11 at 1S andthe end 12 at 19. The blank as shown in Fig. 2 is now ready to beengaged with the elastic member of the garment supporter, shown at 20,and the fastening means shown at 21, by bending the clamp, so that thecurves 1S and 19 embrace the end bar 22 of the fastening means 21, tubes23 and 211 being' formed of said curves, said tubes encircling the endbar 22 and pivotally connecting the clamp with said fastening means 21.Prior to this bending operation the two ends 25 and 26 of the curvedportion 17 of the end 10 of the clamp, are bent at right angles to saidside 10, and when, during said bending operation, the sides 9 and 10 arebrought together, the two curves 16 and 17 form a complete cylindricalopening into which the elastic member is placed, said elastic member inthis instance being a spiral spring, the end of said spiral spring beinginclosed in said cylindrical opening, the inner end of which is closedliange 25, and the iiange 26 being projected between the coils of thespiral spring, thus firmly securing said spring, or elastic member, tothe clamp. In order to maintain the parts in the position just describedthe small tongues or tangs 15, projecting from the side 10, are bentover the side 9 as clearly shown in Figs. 8, et and 5. By the meansdescribed the elastic member 20 of the clamp supporter is securely andpivotally connected to the fastening means or member 21 and the objectof the invention aecomplished.

It will be readily understood that the several parts of the inventionmay be modified by the llO ' in forni somewhat without departing fromthe spirit of the invention, one modified form being shown in F ig. 7 inwhich the fastening means 2l, with end bar 22, the tubes Q3 and 24, theside 9, flanges 25 and 2G and tangs 15 are of the same constiuction asin the other' figures, but additional tangs 27 are formed on the side l0and by preference, in this modification, I would make the tangs l5 and27 somewhat narrower than the tangs l5 before described.

In bending the clamp together to foiin the tubes Q3 and 9.4 around thebar QQ of the fastening means 2l, the elastic member 2O of the garmentsupporter will be secured in the same manner as herein before described,but the inelastic member 28 will be clamped between the sides 9 and l0,the tangs 15 and Q7 passing' through said elastic member and being bentover or clamped against the side 9 in the same manner as before. In thisform both the elastic member 20 and the inelastic member 2S ai'epivotally4 secured to the fastening means 21, whereas in theconstruction before described only the elastic member 2O was so secured,the object of pivotally connecting the fastening means to the supporterbeing to admit of free movement of the parts upon each other when thesupporter is in use.

Having thus fully described my invention,

what I claim and desire to secure by Letters Patent of the United Statesis:

l. )i clamp of the character described' comprising rectangular sides andends, the

ends being formed into tubes to encircle a bar, and the sides beingoutwardly curved to foim a cylindrical opening to receive the end of aspiral spring, one of the sides being provided with a tongue to passbetween tlie coils of said spring, and with a second tongue tol closethe end of the cylindrical opening, substantially as described.

A clamp of the character described comprising rectangular sides andends, the ends being formed into tubes to encircle a bar, and the sidesbeing outwardly curved to form a cylindrical opening to receive the endof a spiral spring, one of the sides being provided with a tongue topass between the coils of said spring, a second tongue for closing theend of the cylindrical opening, and a plurality of tangs adapted to bebent around the other side to secure the parts in position,substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.

BRUN() LAUCKNER.
